Hope this is the right place. Tried to use the search function but...yeah. $10 to ask a question, no thanks.

I have a limited monthly cap on data-usage, so I don't often play online games. Looking at the way TB is set up though, I'm hoping that maybe there's not that much actual data being transferred, but I may just be getting my hopes up. (Since it's just joint states, and not real-time motion?)

If anyone's checked on this, or has some idea of say, MB per hour while connected to an online server, it would be greatly appreciated.

I had a second question as well, somewhat related to the first.

I prefer to avoid downloads of ANY kind unless they're intentional, so how do the mods work. If I load them once, is that mod now in my "inventory", to where I could play Single Player with it even if my internet wasn't connected? Or have all the mods in the list already been dloaded to the game's folders? Or am I re-downloading them every time I switch? (God I hope not)
